Fluoren-9-one oxime
In the title mol-ecule, C13H9NO, the fluorene system and the oxime group non-H atoms are essentially coplanar, with a maximum deviation from the fluorene mean plane of 0.079 (2) Å for the oxime O atom. A short intra-molecular C-H⋯O generates an S(6) ring. In the crystal, mol-ecules related by a twofold screw axis are connected by O-H⋯N hydrogen bonds, forming [100] chains Within these chains, m...
متن کامل3-(9H-Fluoren-9-yl)-1,3-diphenylpropan-1-one
In the title compound, C(28)H(22)O, the fluorene ring system is approximately planar [maximum deviation = 0.044 (2) Å] and forms dihedral angles of 69.88 (6) and 89.46 (6)° with the phenyl rings. The crystal packing is stabilized by weak π-π stacking inter-actions, with centroid-centroid distances of 3.7172 (13) and 3.7827 (11) Å.
متن کامل9-Allyl-9H-fluoren-9-ol
The asymmetric unit of the title compound, C16H14O, contains two independent mol-ecules differing in the orientations of the allyl groups; the corresponding O-C-C(H2)-C(H) torsion angles are -61.01 (13) and -177.43 (10)°. In the crystal, O-H⋯O hydrogen bonds link four mol-ecules into a centrosymmetric tetra-mer, in which each hy-droxy group acts as a donor and an acceptor of hydrogen bonds.
متن کاملBenzo[a]fluoren-11-one
The mol-ecule of the title compound, C(17)H(10)O, is nearly planar, the largest deviation from the mean plane being 0.06 Å. The crystal structure is governed by π-π inter-actions, with centroid-centroid distances ranging from .559 to 3.730 Å.
متن کامل9-Chloromethyl-9-[(9H-fluoren-9-yl)methyl]-9H-fluorene
In the title compound, C(28)H(21)Cl, the dihedral angle between the two fluorene ring systems is 71.97 (4)°. There is an intra-molecular C-H⋯Cl hydrogen bond. In the crystal structure, the centroid-to-centroid distance between stacked fluorene ring systems is ca 4.22 Å, which indicates that there are no π-π stacking inter-actions between them.
